Algebraic Fraction

　　An algebraic fraction is division of one polynomial by another. An algebraic fraction can be simplified by canceling the common factors between the numerator and denominator.

　　Example:

　　(x2-a2)/(x-a)=(x+a)*(x-a)/(x-a)=(x+a).

　　(x2-3x+2)/(x-1)=(x-2)(x-1)/(x-1)=(x-2).

　　Factor out both the numerator and denomin

　　Monomials

　　An expression with only one term is called monomial.

　　Example:

　　3x,2x2,and 4xy are all monomials.

　　2x+1,x+y,3(x+1),and x+x2 are not monomials.

　　Remember:

　　There is no addition or subtraction in monomials.

　　Mono means one, as in monologue

　　ator to find the common factors.
